DefinedNexus by DDTech

A South African WiFi billing system built for hotspot and PPPoE control.

DefinedNexus gives operators one portal to manage hotspot sales, PPPoE accounts, customer records, plans, routers, reporting, and payment workflows without needing a public IP address for management.

Our current focus is 100% on MikroTik, while UniFi and Ruijie/Reyee support are actively in progress.

A billing and management portal for hotspot, PPPoE, customer accounts, plans, routers, and reporting.

Secondary options

Why DefinedNexus Stands Out

A management platform designed for real deployment conditions.

No public IP address is required for management
Works behind almost any connection type
Hotspot and PPPoE management in one system
Integrates with Yoco Payment Gateway and Paystack
Built for practical operator workflows, not just billing theory

Platform Focus

Built around the devices and networks operators use now.

DefinedNexus is currently focused on MikroTik environments, with additional support actively being developed for other vendors.
